In March 2001, Athey Products Corporation was acquired by Federal Signal Corporation. Federal Signal determined that the ongoing production of sweepers would cease upon fulfilling customer obligations under the terms of the sale of Athey Products. It would continue to take orders for service parts and provide warranty and other service relating to product support under the Athey and Mobil name. Athey Products Corporation manufactured heavy-duty equipment and parts. Its principal products include mobile street sweepers and force-feed loaders.
